JOHN DOMlNH 1,312,023, 3 a a we we To all whom it may concern: Be it known that LJOHN DOM-INA, a subject of the King of ltalyyresidingatChicago, in the county of Cook and State .oflljlinois, have invented certain new and -,useul Improvements in Fans, of which the follow.- ing is a specification, r ferenee beinglhad to the accompanying drawings, This invention r lates tocertain improve ments in fans and has relation morepitrticu larly to a device of this general charac ter of a rotary type; and arise-n objeect of the invention to provide "a device of this general character having novel and improved means whereby the salinemaybe readily and ea venient'ly operated through the medium qr a spring motor. r" It isialso an object oftheinvention to provide a device ofthisgeneral character with novel and improved rneanswhereby a rota-i tion offa :ar ae' "d1. VFi alfi Wy bereadily controlled, 1 i

The invention consistsin construction and in the combination and an nei e of th e e al are of p d fa where y seem mpo ta t vantages a e at a ned and "th dev e i i aed si p r, "les l i; aerate otherwi m re bnv nient and F dlvahta QH fa use all as will blc-hereinattermore fully set forth. The novel features of the invention-Will hereinafter be definitely cla i-med.

In order that my inven may'bethe better understood, I will n w proceed to describethe same panying drawirigsQwherem a Figure 1 is a view partly in side elevation and partly in vertical section of a fan constructed in accordance with an embodiment of my invention; a

Fig. 2 is a view in rear elevation of the device as herein embodied with the rear plate or head removed; and

Fig. 3 is a detail fragmentary view partly in elevation and partly in section i11ustrating certain details of construction as herein disclosed. a As disclosed in the accompanying drawings B denotes a base plate of predetermined configuration and dimensions and with which is suitably connected an upstanding post or arm 1 having its upper portion 2 substantially cylindrical in form to afford a head for the cylindrical casin C, said casing being secured to the circu ar portion 2 the detai ed rte re e ate theme a said las are".

T e y 5 and rbtatable ltherearound is the driven wheel orgear 8 adapted to be rotatedby the se ies 3 o a transnation time we Out r 1 pbtti n 07 ai sp ing bei g" nch as at19, to a in w eea at ha ing t was ei is e l0;tothevir d ns hafi a it heige r Qr Whe Sis i mesh w th th fleece w en it ip'o' i meat ab ve and n erti a l ep at w th "th beet e a The ate i alsp many to, a that 2 is not samba leng h 29 d .Iy iafi ae :a an al i arlend LPQ ea i-the sea i ithe tan membe F at any ordinary or preferred type. i i sha t 1% ha i inne and amendin the plate 6 and suitably afiixed "to t named extended portion of the shaft 12 is a disk 15 with which is adapted to eoact the endwise movable member 16 for controlling the operation of the fan. As herein embodied, the member 16 is threaded, as at 17 through the rear head 18 suitably affixed, as at 19, to the casing C. The portion of the member 16 exterior of the casing C is provided with the crank 20 whereby the requisite rotation may be imparted to the member 16 for adjusting the same into or out of contact with the disk 15. It is thought to be self-evident that the member 16 may be adjusted to hold the shaft 12 against rotation under the influence of the spring S or that said member 16 may be so adjusted relative to the disk15 as to vary the speed at which said shaft 12 may rotate. As is. particularly illustrated in Fig. 1,

ten apd f i i ding d i by th plate ;6 h n in e are r crank 22 may be operatively engaged" therewith, the rear head 18 being provided with an opening 23 through which the engaging portion of the winding member or cranlr 22 is adapted to be inserted.

The rear portion of the sh thereto a ratchet wheel 24: with which coacts the dogor pawl 25 pivotally engaged, as at 26, with'the. plate 6,. said dog or pawl-25 cooperating in a well known manner with the :ratchet 24L for holding the shaft 5 against rotation under the influence of: the tension of the spring S. The dog or pawl 25 is maintained in requisite engagement withthe ratchet .24: through the. medium of the retractile member 2? herein disclosed as a conventional coil springanchoredat one end to the dog or pawl 25 at a point intermediate the length of said dog or pawl ,andsecuredatits opposite end. to a'bracket 28or the like" suitably affixed to the plate. 6 and preferably through the medium ofone of the spacing bolts or members 7 The-ratchet 24. 's positioned immediately adjacent,theplate 6 and. suitably aflixed to. the, shaft 5 adjacent the outer face of the ratchet 24 and in contact therewith is a disk 29 of a diameter, .in excess of the diameter of the ratchetf24: which serves to hold thef'dog o rIpawl 25 against undue lateral mo ement" and Fwhereby the requisite coaetion'between. the'dog orfpawl 25 and the ratchet2tl is assured.

. It is. also preferred that dislr 30 be 'aiiixed'to the shaft 12 and in contact with the outer face of the disk 15, said disk 30' being of a diameter less, than the diameter ofthe-disk 15 so that. the periphery thereof affords an, annular shoulder eoacting with the adjacent end-portion of the member 16 for holding the inner end portion of said Vitnesses member 16 against any undue lateral movement lnwardly of the disk 15 so that the desired coiiperation between the member 16 "and-the" disk 15 is maintained.

pensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that my inventionis susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice, except as hereinafter claimed.

Iclaimr V a A device of the character described comprising a base, an upstanding arm carried by the base, a casing in contact with the upper portion of the arm, brackets secured to the casing and the arm for holding the casing to the arm whereby said arm. serves as a head for the casing, a plate positioned within the casing and supported by the arm in predetermined spaced relation relative to the arm, a spring operated driving wheel rotatably supported by the arm and the plate within the casing, a winding and fan shafts rotatably supported by the arm and a braking plate within the casing and operatively connected with the spring operated wheel, and a fanning element carried by the shaft exteriorly of the casing.

In testimony whereof I hereunto ailix my signature in" the presence of two witnesses.
